Readme for the Autodesk 2005 OE Hotfix

Autodesk 2005 OE Hotfix

Drawings with custom AEC objects created in an AutoCAD® 2007-based product and saved in the AutoCAD® 2004 or older drawing
format may display multiple error messages when working with them in an AutoCAD 2005-based product.
This Hotfix suppresses the unneeded error messages.

These error messages are caused by the presence of future-version custom AEC objects that are too complex to be saved back
to a previous drawing format. Proxy representations of these objects are not properly handled by the earlier Object Enablers.
Additional problems when working with these drawings include the inability to bind xrefs in some
circumstances. The custom AEC objects in these drawings cannot be edited and will be visible only if ProxyGraphics are
enabled when the drawing is saved from the original application.

For more information about custom and proxy objects, see the "Work with Custom and Proxy Objects" topic in the
AutoCAD Help system. Enter "proxy objects" on the Search tab.
